On-farm experiments were carried out for three consecutive seasons in 13 villages in the forest zone of central Cameroon to assess the above parameters. The treatments evaluated were three improved maize varieties (CMS 8501 and CMS 8704 developed by IRAD, and AK 9522- DMR developed by IITA) plus a local check used in the village. A one-farmer one-replicate approach was used with the varieties being arranged in a randomized complete block design. Results showed that improved varieties were significantly less infested than the control. Mean grain yield was significantly higher for improved varieties than for the local check. However, no significant difference could be found among the high yielding varieties although the mean grain yield differed in the order CMS 8704 > AK 9522-DMR > CMS 8501. The same trend was observed for the marginal cost benefit ratio (MCBR) as derived from the partial budgetary analysis. These results suggest that CMS 8704 performed best as compared with the other varieties tested. However, based on farmers' perception of production and taste characteristics, AK 9522- DMR was the best, followed by CMS 8704, CMS 8501 and local variety. This suggests that if these varieties were to be adopted by the farmers of Cameroonian forest zone, the adoption would follow the same sequence.Collection: CIMMYT Publications Collection
